KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf die Herstellung einer Masse, die als Ersatz für Leder, insbesondere Kern- und Sohlenleder, dienen kann.The invention relates to the production of a mass that can be used as a substitute for leather, in particular core and sole leather, can serve.
Man bereitet zunächst auf folgende Weise zwei getrennte Mischungen:First, prepare two separate mixtures in the following way:
a) Man mengt ioo (Gewichts-) Teile Celluloidkitt (Auflösung von Celluloidabfällen in Amylacetat) mit. 5 Teilen flüssigen oder gelösten Kautschukes und 10 Teilen Fischtran oder Glycerin und knetet oder rührt die Masse so lange, bis sie etwa die Konsistenz von Glaserkitt angenommen hat. Die Masse wird dann innig mit 31,5 Teilen Metallfeilspänen (Eisen, Stahl, Aluminium o. dgl.) vermischt. a) 100 parts (by weight) of celluloid cement are mixed together (Dissolution of celluloid waste in amyl acetate) with. 5 parts liquid or dissolved Rubber and 10 parts of fish oil or glycerin and knead or stir the Mix until it has about the consistency of glass putty. The crowd is then intimately mixed with 31.5 parts of metal filings (iron, steel, aluminum or the like).
b) 100 Teile Dextrin oder Balata oder ein ähnliches Bindemittel werden mit 10 Teilen Altgummipulver, 10 Teilen tierischer Sehnenwolle und 10 Teilen gepulverten Lederabfällen zu einem dickflüssigen Brei angerührt.b) 100 parts of dextrin or balata or a similar binder are mixed with 10 parts Waste rubber powder, 10 parts of animal sinew wool and 10 parts of powdered leather waste mixed to a thick paste.
Die beiden Massen, die vorteilhaft lederartig gefärbt werden, knetet man . zu einem steifen Kitt zusammen. Dieser erstarrt zu einer elastischen Masse, die das beste Sohlenleder weit an Haltbarkeit und Festigkeit übertrifft.The two masses, which are advantageously colored leather-like, are kneaded. to a stiff putty together. This solidifies to an elastic mass, which is the best sole leather far exceeds in durability and strength.
Um einen möglichst vollkommenen Ersatz für Sohlenleder herzustellen, verfährt man am besten wie folgt:In order to produce a replacement for sole leather that is as perfect as possible, one proceeds preferably as follows:
Man nimmt zwei wertlose dünne Felle von Kaninchen, Hammel, Ziege o. dgl., befreit sie von Haaren und imprägniert sie zunächst mit einem Harz, einer Harzlösung, Teer oder einem anderen wasserabstoßenden Mittel. Die Felle werden dadurch wasserdicht, zugleichYou take two worthless thin skins from rabbits, mutton, goat or the like and free them of hair and impregnate it first with a resin, a resin solution, tar or another water repellent. This makes the skins waterproof at the same time
werden die Poren dehnbarer und die Felle im ganzen elastischer, wodurch die innige Verbindung der Felle mit der vorher beschriebenen Masse wesentlich gefördert wird.the pores become more flexible and the skins more elastic as a whole, creating an intimate connection the skins with the previously described mass is significantly promoted.
Man nimmt jetzt eine Form, die der Größe der beiden Felle entspricht, legt das eine Fell mit der glatten Seite nach unten hinein und breitet die oben beschriebene, aus a) und b) gemischte Masse darauf aus, und zwar ungefähr in der Dicke, die man dem künstlichen Leder zu geben wünscht. Auf die Masse deckt man das zweite Fell, mit glatter Seite ebenfalls nach unten, also mit der rauhen nach außen, und unterwirft nun das Ganze einem Druck von etwa 100 kg/qcm, worauf man trocknen oder erstarren läßt.You now take a shape that corresponds to the size of the two skins, and lay one skin with the smooth side down and spread the above described from a) and b) mixed mass on it, about the same thickness as that of an artificial one Wishes to give leather. The second skin is covered on top of the mass, with the smooth side also downwards, i.e. with the rough one on the outside, and now subdues the whole thing a pressure of about 100 kg / qcm, whereupon it is allowed to dry or solidify.
Auf diese Weise erhält man ein Erzeugnis, das genau das Aussehen von echtem Leder hat, aber dieses an Haltbarkeit und Festigkeit bei weitem übertrifft.In this way you get a product that exactly looks like real leather has, but far exceeds this in terms of durability and strength.
Es versteht sich, daß die angegebenen Mengenverhältnisse nicht absolute Bedingung für die Gewinnung eines Produktes mit den angegebenen Eigenschaften sind, vielmehr innerhalb gewisser Grenzen abgeändert werden können, ohne daß von der Erfindung im wesentlichen abgewichen wird.It goes without saying that the specified proportions are not an absolute condition for the production of a product with the specified properties, rather can be modified within certain limits without essentially departing from the invention.
Jedoch ist zu sagen, daß sich die angegebene Zusammensetzung auf Grund von sorgfältigen und lange fortgesetzten Versuchen als die beste bewährt hat.However, it should be said that the stated composition is based on careful and long-term attempts has proven to be the best.
Es sind schon viele Lederersatzmittel vorgeschlagen worden, die Celluloid, Kautschuk und Füllmittel, wie Korkmehl u. dgl., enthalten; auch der Zusatz von Lederabfällen, der ja besonders naheliegt, ist nicht mehrMany leather substitutes have already been proposed, the celluloid, rubber and fillers such as cork flour and the like; also the addition of leather waste, which is particularly obvious, is no longer
neu. Die nach den bekannten Vorschriften hergestellten Produkte lassen sich aber weder an Festigkeit noch an Elastizität mit natürlichem Leder vergleichen. Dies kann teils an der Wahl der Füllmittel, teils an den Bindemitteln liegen. Es ist z. B. klar, daß . man bei Verwendung von Korkmehl als Füllmittel höchstens linoleumartige, d. h. brüchige Produkte erhalten kann. Das Bindemittel ίο muß so- gewählt werden, daß es niemals zu einem spröden Stoffe erhärtet, sondern schmiegsam bleibt, aber doch eine hohe Zerreißfestigkeit gewinnt, und diese Eigenschaften hat die hier beschriebene Mischung.New. However, the products manufactured according to the known regulations can neither Compare with natural leather in terms of strength and elasticity. This can be partly on the choice of fillers, partly on the binders. It is Z. B. clear that . when using cork flour as a filler, at most linoleum-like, d. H. brittle Products can get. The binding agent ίο must be chosen so that it never becomes hardens to a brittle substance, but remains pliable, but still has a high tensile strength wins, and the mixture described here has these properties.
